Xindium Unveils Improved RF Power Amplifier Module for Use in GSM and GPRS Cell Phones.CRYSTAL LAKE, Ill. -- New Component Features Integrated Power Control, Allowing for Simplified Handset Manufacturing Process Xindium Technologies, a leading developer of advanced RF power amplifiers for mobile phones, has introduced a new power amplifier module, providing GSM and GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. handset manufacturers with a new source of RF power amplifiers that offer industry-leading performance. The new power amplifier module, called the XPA XPA Xeroderma Pigmentosum, Complementation Group A (protien) XPA X Public Access XPA Extra Points Attempted (football) 9133, is a quad-band, 7-by-10 mm GSM/GPRS InGaP HBT HBT Heterojunction Bipolar Transistor HBT HyCult Biotechnology (Uden, The Netherlands) HBT Hanbury-Brown-Twiss (interferometer) HBT Herring Bone Twill HBT Heflex Bioengineering Test device with integrated power control, featuring best-in-class efficiency and ruggedness. The XPA 9133 features a pinout and a power control scheme that are similar to the current generation of 7-by-10 mm GSM/GPRS power amplifier modules, reducing the need for changes in circuit board design for GSM handset manufacturers. Xindium is working with leading PA power control vendors to provide handset-ready PA/power control reference designs to GSM/GPRS handset OEMs and ODMs. These reference designs support either precision closed-loop power control or low-cost open-loop power control, with the burst and ramp profile quality necessary for high-yield volume handset manufacturing. "The XPA 9133 gives manufacturers greater diversity in their PA supply base without compromising on cost, performance, size, or manufacturing yield," said John Brewer, Xindium CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. . "This power amplifier module demonstrates Xindium's ability to be a leader in the GSM power amplifier module market, and represents an excellent addition to Xindium's industry-leading InP DHBT DHBT DHB Capital Group, Inc. (stock symbol; previously DHB) DHBT Double-Heterostructure Bipolar Transistor technology base." The XPA 9133 PA module provides nearly 60 percent efficiency at maximum output power for GSM900, and over 50 percent efficiency for DCS (1) See also DSC. (2) Digital Cross-connect System) A network switching and grooming device used by telecom carriers. See digital cross-connect. . The XPA 9133 supports tri-band and quad-band applications utilizing any combination of the GSM850, GSM900, DCS, and PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. bands. The XPA 9133 PA supports GPRS Class 12 operation. In quantities of 10,000 units, the XPA 9133 is priced at $2.40. About Xindium Technologies Xindium (www.xindium.com), is based in Crystal Lake, IL, northwest of Chicago. Xindium designs and markets advanced RF power amplifiers for next generation mobile phones, allowing faster, more reliable high-speed wireless data transmissions, such as Web browsing, downloading music, or emailing photos. Xindium is developing indium phosphide phosphide Any of a class of chemical compounds in which phosphorous is combined with a metal. Phosphides exhibit a wide variety of chemical and physical properties. Phosphides that are rich in metal have high melting points and are hard, brittle, and chemically inert; these (InP)-based power amplifiers for next-generation EDGE and WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. wireless networks. Xindium's power amplifiers redefine RF power, efficiency and linearity for the EDGE market, enabling EDGE mobile phones to transmit high-speed data applications, such as video, music, voice-over-IP, and Web sites, reliably over wireless networks. Xindium also offers a gallium arsenide (GaAs)-based power amplifier design for the quad-band Class 12 GPRS handset market. This power amplifier, which is identical in performance and cost to power amplifiers from leading vendors, provides a transitional solution for today's mobile phones while the industry moves toward future wireless networks. Later in 2005, Xindium will introduce an InGaP HBT-based quad-band PA module for EDGE handsets. |
